ALPS Mountaineering Sleeping Bag Liner

Warm and cozy. Bought this to address a ~10° shortfall experienced with my sleeping bag. I couldn't quite figure how a thin sheet would make much of a difference in heat retention, but a friend convinced me to take the risk. Turns out it sure does the trick! Not only was I warm and comfortable, the fabric feels great on my skin. Well worth the additional pack weight.

Great item fit in sleeping bag without being to tight or having excess. Makes cleaning sleeping bag easy

Not sure about this purchase. Some reason I thought the mummy version would open along the side. But this is basically a big sock. You climb in to this thing.It’s soft for sure. Has a decent amount of room. Biggest issue is only one way to get into it.

This worked very good. Added a bit of warmth to the sleeping bag and of course avoid it getting dirty

It's what I expected it to be, either a thin sleeping bag that can be used on its own or a liner to be used inside a thicker sleeping bag. It feels like bed sheets stitched together to form a sleeping bag.

I thought it would be a flece bag to keep me warm. But it wasn't even a soft material. It felt like plastic. I returned it.

Cheaper than the sea to sumit brand but very good. Feels just like a microfiber bed sheet. Worked very well with a 30 degree marmont tressled elite that is confort rated to 38 at philmont. It was not even most likly needed for philmont.

I was hoping this would provide a bit of extra warmth when using with my sleeping bag, however upon receiving it became clear that this would not provide any additional insulation whatsoever, just act as a barrier between my body & the bag. Imagine if you took the top sheet off of your bed & sewed it into the shape of a sleeping bag - that's essentially what this is. This could be what some people are looking for, but not me, so I returned it in exchange for a sea to summit thermolite liner.
